Well yes it was a contentious production, but I think Peck and Bergman have poor chemistry and the psychological diagnosis/cure things usually tend to be cheesy (even in Psycho, and in Marnie as well).
The Dali thing is cool, but that's a pretty small part of the film.
Stage Fright is very underrated and has some interesting narrative trickery on Hitch's part. I Confess was really championed by the French New Wave critics, and the location work in Montreal is refreshing.
Ehh...whatever its faults, it's still very powerful as cinema. For the direction alone I wouldn't put this near the bottom.
This. Though it could have used a bit more humor. Kubrick's had WAY too much, Sellers never should have been allowed to run wild like that. Imagine Robin Williams instead of Frank Langella in the Lyne version because that's essentially what it was.
Well considering The Shining is widely regarded as one of, if not the, greatest horror film(s) ever, I wouldn't feel comfortable describing it as the worst. Can't judge it as an adaptation, can we? How faithful was Barry Lyndon to its source? Or Eyes Wide Shut? I've said this before, Kubrick is more important than Stephen King so I don't give a fuck how he alters the latter's work.
Full Metal Jacket, on the other hand, is NOT widely regarded as one of the best war films, and is considered redundant by many considering all the Vietnam films that had come before it. While there are some great scenes, overall I don't find it to be as successful an endeavor as The Shining. Also, Spartacus is a film that Kubrick was brought on late, and did not have complete creative control on. For that alone I'd rank it lower than most of his films.
Personally:
1. 2001: A Space Odyssey
2. Eyes Wide Shut
3. Dr. Strangelove
4. Paths of Glory
5. A Clockwork Orange
6. The Shining
7. Barry Lyndon
8. The Killing
9. Spartacus
10. Full Metal Jacket
11. Lolita
